Energy Conservation: Why It's So Important
There is no way for you to have not noticed that your bills have been increasing. It has happened and is one thing that you just should consider doing. But, energy conservation is not always something that is on our minds. If you find yourself only thinking about it when the bills for the month arrive, then you may be missing the boat.
Why You Need To Know
Energy conservation is helpful in a number of ways to each of us. The most profound way that affects us directly is the cost. If you just turn off a few lights, you may not notice it. But, if you do several things to keep yourself in line with your energy goals, you may find yourself able to really save money here. Energy costs continue to rise and even if they slow down in that rise, they are not likely to come down. If you want to cut your bill down, then, you must use less energy.
Yet, there are other reasons for conserving energy as well. Consider, for example, the fact that one of the most vital fuels that we all rely on is that of oil. Some scientists believe that we will run out of oil within the next 60 years. Can you image the cost of your bills then? Still, consider the fact that many of these energy needs also produce toxins in the air. That makes them not only running out but also destroying the environment while they do it.
As you can see, there are many reasons why you, as a citizen of Earth should consider energy conservation in your daily life. Even if you just cut back slightly here and there, you will notice a difference in your bill but not necessary in your overall lifestyle. There are many benefits to taking care of the energy we use. It is a good thing for all of us to take into consideration as well. The end result is a result that satisfies everyone's needs.
Find a few ways that you too can cut down on the amount of energy that you use. Challenge yourself to a few different limits. See if you can save just $5 this month on your electric bill. See if you can conserve energy for your own and for the world's well being.

Sustainable Development in the words of Brundtland report is "the development that meets the needs of the present without compromising the ability of future generations
To meet their own needs ".
In this context nuclear energy as a future energy source has occupied centre stage of
India's concern. The characteristics of nuclear energy, it's economic, environmental
and social impact and its link to sustainable development have come under the scanner of economic and political debate in the recent times.
This paper entitled "Sustainable Development and Energy Security" attempts to explore the prospects of adopting nuclear energy as a future energy source to meet the India's
growing energy needs. Nuclear energy, though requires large capital investment in form of nuclear power plants, is seen as an alternative to fossil fuels. Use of nuclear energy not only meets the growing energy demands, but also minimizes the environment and social burdens.
Nuclear energy does not have environmental effects on global warming, green house effect, climate change and pollution. Hence the central goal of sustainable development i.e.maintainence and development of natural, human and social assets will have been met by use of nuclear energy.
This paper analyses the following aspects:
Various forms and sources of energy.
The role of energy in economic development.
The problems of developing countries vis-à-vis energy security.
Nuclear power and its importance in the light of power shortage in India in the context of sustainable development.

1. SUSTAINABLE DEVELOPMENT AND ENERGY SECURITY
1) Introduction
India's energy resources are mostly available in convenient form. India has a
Significant reserves of coal, its electricity generation is also significant
Today more than 70% of power generation is through burning of coal.
We have 221 billion tones of coal reserves .India has a large hydro potential and only a part of this potential has been exploited .as per department of atomic energy of India ,India as also good uranium deposits supporting growth of "Nuclear Energy". India is growing giant facing the critical challenge of meeting a rapidly increasing demand for energy .
India ranks 6th in the world in terms of energy demand and our economy is projected to grow 7% to 8% in next two decades .the international energy agency projects indias dependence on oil imports will be more at 91.6% by the year 2020 and India is relatively poor in the oil and gas resources . Even though there are several problems associated with energy in India from 1951 to 2005, it has produced coal 12 times greater then what was available in 1951 crude oil production increased 110 times. And the electricity installed capacity had a growth by over 68 times.
India has to meet two big challenges for a sustainable development .firstly it should meet the increasing demand for energy resources in the country .secondly it should avoid all environmental hazards and its should ensure an energy security by conservation of energy so that the future generation can also meet their wants for energy resources with available stock .this can lead to long term economic development which indicates the "Sustainable Economic Development" on which our attention is much more needed.
2. SUSTAINABLEDEVELOPMENT
The concept of sustainable development was elaborated in the late 1980.
The tern sustainable development was brought into common use by the world commission on Environment and Development in its seminar report called
"Our common Future". Brundtland Commission defines sustainable development as "Development that needs the needs of the present generation without comprising the ability of future generation to meet their own needs.
We can understand that use of the concept "Needs" in the definition is linked with the distribution of resources through three components of man made capitals, human capital and natural capital & it aims to achieve sustainable development through integration of three dimensions in a balanced way.
According to Professor Barthwal of ‘Indian Institute of Technology, Kanpur' has highlighted some important indicators of sustainable development there are as follows:
1) GDP growth rate.
2) Population Stability.
3) Human Resources Development Index.
4) Clean Air index.
5) Energy intensity.
6) Renewable energy proportion.
7) Material intensity.
8) Water use.
9) Soil degradation.
10) Forest coverage.
11) Re-cycling proportions.
12) Transport intensity.
These indicators show the changing trends of an economy towards Sustainable Development. Let us discuss this concept from the point of view
Of Energy Security and adopting Nuclear Energy as a future Energy Source which is the latest Debate in our country.
2) FORMS OF ENERGY
Energy has several forms which is useful to all human beings:
Mechanical Energy: Like kinetic and potential position against resistance.
Heat Energy: Can cause gases to expand, can melt the metals and convert water into steam.
Radiant Energy: Include light, radio, X-Rays, Laser etc.
Electro-magnetic Energy: Flow of electrons producing an electric current.
Chemical Energy: Stored in molecules of Food or in fossil fuels such as coal and oil.
Nuclear Energy: The force that combines the atomic nucleus together it is obtained through Fusion and Fission.
These energy are inter-convertible but it incurs a economical expenses which may not be profitable also Ex: Electrical Energy into light or heat Energy.
3) SOURCES OF ENERGY
Energy Sources refers to the sources from which energy is obtained to provide heat, light and power.
Renewable and Non-Renewable Energy sources:
Non-Renewable Energy sources are those which are lost in one operation the called depletable or exhaustible sources of energy their availability s always fixed and they are always at a declining stage Ex: Fossil fuel.
Renewable or In exhaustible energy sources are those which are perennial in nature they are regarded as flows rather than as stocks their total supply cannot be more than the available flow and the flow is perennial.
Ex: Hydro-electricity.
Commercial and Non-Commercial Energy Sources:
Commercial Energy Sources we include all those sources which are supplied through formal and organized Industries and marketing channels.Ex: Coal, Petroleum, natural gas which do not result in production, distribution and consumption or strictly passed through exchange Ex: fire wood, agriculture straw and animal waste etc.
Conventional and Non-conventional Energy Sources:
All those sources which the mankind is used to using are called Conventional Sources which those which are in their sources which those which are in their introductory stage or which can be used in future are called additional, alternative, or Non-Conventional Energy Sources.
Commercial sources of Energy play a vital role in developing country like India for Economic Growth and later in development.
4) TRENDS IN THE PRODUCTION OF COMMERCIAL ENERGY (1950-51 TO 2004-05)
Energy is the a vital resource for the economic development the production of commercial energy has increased steadily after introduction of economic planning and energy sector reforms in
"New Economic Policy" in 19191.from 1951 and 2005 coal
Production has increased by nearly 12 times, crude oil production by
110 times and electricity [installed capacity] by over 68 times.

Important points:
a) The transport sector was the largest consumer of commercial energy but in later stages there is a fall in total energy consumption.
b) The industrial sector has become largest consumer of commercial energy in the country.
c) Agriculture sector has also increased the total consumption of commercial energy.
However according to Indian planners we require:
I. 412 million tonnes of oil equivalent [mtoe]in the year 2006-07
i.e. the terminal year of the Tenth five year plan.
II. 564mtoe in the year 2011-12 which is the terminal year of the Eleventh plan.
In India even though the production of commercial energy has increased but the population ,industrialization, urbanization has increased much more at a greater rate and its total consumption is more so India is facing energy crisis.
6) Energy Crisis in India.
In Indias economic development energy crisis are in the form of oil
Shortage, coal shortage and power shortage.
a) Indias energy problem arises due to imbalance in demand –supply of all commercial fuels with increase economic growth the consumption of energy is also increased at a rapid rate though ONGC [oil and natural gas commission] have implemented several policies of exploration and increase of indigenous crude the consumption petroleum and oil products has far exceeding the indigenous production and refining capacity therefore is energy crisis.
b) The coal industry performance has been failing badly in recent years the coals reserves are poor , both in quality and in quantity
c) The creation and distribution of electricity generation in India has a poor performance where it is not able to meet the growing demands of both industrial and agriculture sectors.
d) The performance of government local boards in distribution of electricity is also very poor; there is theft, pilferage and wastage of use of electricity both in urban and rural areas.
e) The production of energy through different technology is not perfect; much of the energy is lost during transferring those4 energy sources to ultimate use.
These features for energy crisis in India and slow economic development.
7) Basic problem of Indian economy associated with energy:
a) Increasing consumption of commercial energy.
b) Domination of using non-commercial sources of energy [I.e. in the rural areas ]
c) Unequal distribution of energy.
d) Inefficient use and under utilization of energy.
e) High dependence on foreign countries especially on Arabian countries.
8) Energy Security.
Indias long term aim of energy security will be primarily about ensuring
the continuous availabity of commercial energy at competitive prices to
support its economic growth and meet life line energy needs of its house
holds with safe, clean and convenient forms of energy even if it entails
directed subsidies.secodly reducing energy requirement and increasing
efficiency are two very important measure to increase energy security.
Energy security is concerned dealing with various risks I.e. supply
Risk, market risk, technical risk, etc
a) Supply risk are those risks originated with the uncertainty of imported energy where India is mostly depended on foreign countries for oil imports
b) Market risks those risks arising through fluctuations in price of energy even though the country has adequate energy resource.
c) Technical risks can be the technical failures which may disrupt the supply of energy generations could fail, transmission lined may trip or oil pipelines may spring a leak.
Therefore Indian needs much attention and security towards these types of risks and ensures that wastages of energy through these risks does not hamper the growth of the economy and cause hazards to environment.
In India energy security is much needed from the house hold level.
House hold energy security : clean fuel for all ;we may set up goal to provide clean cooking energy such as LPG,NG,Bio gas or kerosene to all within 20 years and ensure they use these energy for right domestic use which gives a energy security .
Currently India consumes 0-16kg of oil equivalent [kgoe] per dollar of GDP expressed in terms of purchasing power parity.
India s energy intensity is lower than the 0.23 kgoe of china,0.22 kgoe of U.S and a world average of 0.21 kgoe .this comparison conforms that there is a room to improve and energy intensity can be brought down significantly in India we can fallow these aspects like ,
a) Lowering energy intensity through higher efficiency is equivalent to creating a virtual source of untapped domestic energy and aggressive pursuit of energy efficiency and conversion ,it is possible to reduce indias energy intensity by up to 25% from current levels
b) Efficiency should be increase in energy extraction, conversion, transportation, as well as in consumption.
c) Ensuring proper labeling on the equipments if the equipment fails to deliver the stated efficiency proper financial penalties should be imposed.
d) Established benchmarks of energy consumption for all energy intensive sectors.
e) Promote minimum life cycle cost purchase instead of minimum initial cost procurement by the government and the public sector.
The failure of energy sector to meet the increasing intensity of demand is considerable falling to extent. this was due to the lack of importance given by our 5year plan because they did not give long term policy imperatives in energy planning .our 8th plan gave importance to long term integrated planning here the emphasis was laid both on efficiency strategy of long run energy supply and energy end use .
Our planning commission realized the following drawbacks of unplanned measures about energy security it mainly turned its attention towards; 1) gradual shift from non renewable energy sources to renewable one.2) the emphasis was laid on energy conservation and management of demand and efficient utilization of energy resources .3) distribution of energy needs high priority in meeting the basic energy needs of the rural and the urban poor in the immediate future.
According to Jyoti Parikh and Kirit Parikh," the critical problem today lies in increasing the efficiency of use of resources the inefficiency in the use of created capacities have undermined the financial viabilities of energy sector units public sector units seem to be unable to deal in a commercial manner with users with political clout reforms, therefore have to involve in situational arrangements."
9) Strategies for Energy Security in Future:
The main problem of India is that we are much dependent on crude oil on foreign countries we should organize more research and development programmers so that we can explore our potential to meet our domestic energy demand
The government of India has come up with some strategies like:
Exploration in new areas like exploring in the deeper layers of the producing fields exploring in new areas of deep water and difficult frontier areas.
The newly discovered fields has to be properly developed by using modern new technology in producing areas
The methods and technologies must be upgraded for improving existing major fields.
Using alternatives sources of energy such as :
Coal bed methane.
Gas hydrates.
Underground coal gasification.
Shift to natural gas and NG.
Ethanol made from sugar.
Bio- diesel extracted from jetropha, karanja tree etc.
Even though policies are made and government has taken initiatives in strict
areas of energy conservation and management of oil demand and ensuring
proper measures to have energy security Indias demand from energy sector is
increasing at a rapid rate therefore the best choice adopted by all our Indian
Planners and government is to select an another energy sources which is clean
energy and operating cost should be moderate and Indian environmental hazards
such as ozone depletion, and green house effect, and acid rain faced by use of
fossil fuel are minimized the best outcome of this decision is the "Use of
Nuclear Energy" which can lead to long term economic development
This can contribute to sustainable economic development.
10) Nuclear Power For India.
India progress in recent years after the introduction of new economic policy is no doubt a progressive development for maintaining our current economic growth rate of 8% to10%per annum we should solve the problem of inadequacy of energy supply which is a major constraint on accelerating indias growth rate .
The 123rd agreement between India and united states of America had contributed some valuable hopes towards achieving the dual objectives of our nation .firstly to ensure the challenges of energy security .secondly to achieve the objectives of environmental sustainability. there fore India's nuclear programme was founded to address the challenge of energy security and attain self reliance and technological independence.
11) Nuclear Energy is also Clean Energy.
In India there is high dependence on use of fossil fuel and the rich use of
Fossil fuel have definitely contributed to environmental hazards .most of the
scientists agree that pollution is contributing to global warming and to
climatic change to minimize these burdens our environment requires a
clean and green energy like "Nuclear Energy".
In India even producing electricity involves huge wastages and
Environmental hazards .Nuclear energy is best energy that has taken the full
Responsibility of disposal of all its wastages and meeting its full cost of
Doing so .Nuclear energy does not contribute to global warming the cost
Of the fuel for a nuclear power station is very economical compared to
an equilivalent coal fired power station .the electricity generated from
nuclear reactors is competitive with electricity produced from coal, even
after providing for management and disposal of radio active wastages and
the decommissioning of reactors so, Nuclear energy will be a clean and an
affordable source of energy.
12) Scope for Nuclear Energy in India.
In India at present only 3% of India's energy needs are met from nuclear sources
India plans to produce 20,000 mwe from the nuclear sector by 2020 increasing from the very low level of 3700 mwe at present.
The increased share of nuclear power in the Indian energy mix will diminish the reliance on fossil fuel and reduce carbon emissions from India.
13) Growth and Performance of nuclear Plants in India.
The tarapur plants, unit one and unit two and Rajasthan atomic power plant are
The major power plants in India let us see the trends in the growth rate of

14) Role of Nuclear power.
Nuclear power has definitely contributed to increase in electricity and
It is likely to increase more the plans to meet the increasing production
of energy was attempted in two ways: firstly the department of atomic
energy gave importance to use of domestic uranium resources in
pressurized heavy water reactors (PHWRs).secondly on an imported
technology light water reactors was setup at kundankulam in Tamil
nadu for this purpose .to exploit the vast thorium reserves in the country
Bhaba Atomic Research centre developed a 300 Mve advanced heavy
Water reactor for this purpose .therefore nuclear power has good
Technology in India with very significant potential for avoiding the
Burning of large quantity of poor quality coal .the uranium and
thorium resources are more in the country and use of fast breeder reactors
thorium reactors which can tap the full energy potential in nuclear energy
materials through the use of recycle technologies has contributed towards
creation of extra energy for increased economic growth.
15) Safety of Nuclear power.
India today, It has been operating with 200 Nuclear reactors with a
Record of safety in its environment. The Atomic energy regulatory board
In India as per the directions of International Energy Agency works on
Established line of standard so safety is maximized with extra care
Unless there is failure in transferring nuclear power plants and
problems of radioactive causes of nuclear power plants –Nuclear
energy is very safe to use in any economy.
16) The Economics of Nuclear Power.
The unit energy cost of nuclear power compared to power from coal
At locations away from coal pits are economical high capacity factors,
low discount rates and reduced capital costs are factors, which make
nuclear power more attractive and conditions in India for improvement of
nuclear power in good, with its low variables nuclear power improves
its relative economics with year of operation of the power plant.
17) Suggestions:
To be always dependent on foreign countries for crude oil is not secured
Economic activity .we should create our own opportunities to meet the
Domestic demand.
There must be an gradual shift from the use of non renewable sources
of energy.
The Research and Development programme must be conducted for exploiting the potentials of non – conventional sources of energy ,
Exploration is must in areas of estimated energy availability.
The technology used in creation ,generation and transferring of
Energy should be upgraded.
Economic planners should give long term planning in energy supply sources to meet basic demands of economy etc.
18) Concluding Remarks:
India's fuel resources position definitely invites development and
deployment of nuclear power programme .nuclear energy will definitely
Contribute to the long term success of sustainable development
the technology to harness nuclear power are still under the
modernization stage in India, effective government support is definitely
needed in terms of increasing the efficiency though our power sector
makes an considerable growth, our rapid industrialization and improved
agriculture and quick changes in population is more than the energy
generations hence consumption is more than supply and production.
this should not be a continuing increasing trend in future the steps and
measures to control this situation will definitely contribute to the long
term economic development of India which is nothing but
"Sustainable Development".

Why These 3 Renewable Energy Sources Are Not Going To Bring You Profit - Learn The Facts
There are three major renewable energy sources - wind power, solar power, and magnetic power. Recently, there has been a lot of hype surrounding these with promises that you can make your own electricity using each of these. Even more, some claim that you can make so much electricity that you have a surplus and you can sell it to your power company. All these claims are probably well-founded in facts. The purpose of this article, however, is to present you with the shortcomings of each of these three sources, so that you can make a better decision based on a careful consideration of pros and cons and not only hearsay.
What is wrong with wind power systems?
In theory wind power systems can make you a lot of free electricity whenever the wind is blowing. Stop. Do you see the first shortcoming? Yes, the wind has to be blowing. If it is not blowing for some reason, then you are not making electricity anymore. Therefore, the first shortcoming of wind power is its over-dependence on its source - the wind. Whenever there is no wind, there is no electricity. With this, obviously, you can not go completely off-grid.
The second shortcoming of wind power systems is connected with the price of such an installation. How much do you think it would cost you to purchase a wind turbine and to set up your wind power system? It can certainly cost you well within the tens of thousands of dollars. And how long will it take for this system to repay for itself? Well, let us say that you save $100 per month, which is a reasonable amount - not too much, not too little. This makes a little over $1000 per year. So depending on the price of your system you are set for up to 20-30 years for your system to repay for yourself. Do you have so much time to wait?
Now, how about solar power systems?
Yes, it is quite similar to wind power. In the case of solar power, however, you need not wind but sun exposure for it to make you electricity. If the sun is shining, you are making electricity. If it is not shining, though, you are stuck without electricity. Therefore, you can not really go off-grid with solar power either.
Price is another big factor in solar power systems as well. They are pretty expensive - perhaps even more expensive than wind power systems. The initial investment of tens of thousands of dollars takes a while to repay itself unless you are really lucky and you get a lot of solar exposure. So similarly to wind power, solar power systems take a long time to pay for themselves and are not reliable to give you electricity all the time. Do you want to get stuck with such an expensive and sometimes inefficient system?
Finally, let us look at what is bad about magnetic power systems?
Magnetic power systems are the cheapest of the three. However, the bad thing about them is that you have to build them yourselves, i.e. presumably not everyone can build one. So you need know-how. Where do you get this know-how? And is it going to allow a complete newbie make a well-working magnetic power generator?
But there is one more shortcoming of magnetic power generators, and that is their efficiency. We already mentioned the low price. Well, you get what you pay for, so the return is not that high either - it takes several hours to charge a simple 12V battery. Therefore, magnetic power generators are definitely not sufficient to go off-grid and stay off-grid.
So, these were the shortcomings of the three top renewable energy sources. One could easily see that each of these has its shortcomings. But what if you were to implement all of these, so that they could complement each other. Furthermore, what if you had a step-by-step guide on how to make each one of them? Thus, you could save money and you could make sure that your renewable energy system is most efficient. For a list of renewable energy DIY systems check the link below.
Steps to Get Green Energy Grants From the Government
People are discouraged from developing new sources of energy because of the costs of the new technology is so high. To convert energy from the fossil fuel to renewable energy is so expensive. But still, the benefit of changing the lifestyle into using the green sustainable energy can be seen in the future, therefore the government is actively encouraging people by providing help which can be used in buying and installing the green energy equipments. If changing the future of the next generation is one of your biggest interests, then you should apply for the green energy grants. The application can be obtained online. You can choose from many types of grants provided by the federal government.
Steps to get the green energy grants are:
1. You must register at the website that provided grants for you. Enter you username and password to login. When you are already submitted to the website, you can check your application for the grant's process.
2. Do some researches on the United States grants website of federal government. Simply by entering the type of the green energy that you are going to apply in the field of search. You also can do this by browse the section of ‘energy' to find the type of your green energy grants. The advanced search is the other way to find the grants. But with this search, you should specify your status like ‘public housing authorities', ‘individual', ‘small businesses', ‘for profit organizations other than small businesses', or non profits'.
3. They might not have opened the application for grants at some time; therefore you should sign up for subscription of email to get updates for grants. The information will change quickly, so you need to get the newest information on the grants as fast as possible. The grants are also available on RSS feed, so make sure you get the grant tomorrow if you can't get it today.
4. The application for the grants can be downloaded; it depends on your need. There is an application specific to each grant. You should be careful on downloading the right form and carefully read the instructions. There are also different instructions for each grant.
5. You can fill the application offline, but if you don't want to do it offline, you can go online. But you must remember that the website does not save your online filled progress. Careful to make mistakes while filling the application for grants green energy online.
6. Submit the finished and corrected application to the grants site. Check for the confirmation email, you will also get another email in 24 hours to validate your application.
7. You should just have to wait and don't forget to track the online progress.

hmmm i can't come up with a science fair project... can you help?
I want it to be something about the enviroment or going green... it can be an experiement or research project... any ideas? i was thinking designing a "green" house with energy efficent apliences and such... i'm welcome to more ideas
Build a Van de Graff generator. You need a plastic pipe(PVC) The bottom wheel needs to be plastic or cloth. The top wheel needs to be metal. Put as round a piece of metal you can find on top. And WALA! You just built an electrostatic generator. Just forget the motor and use a hand crank to power it(just so it's green) And a final tip, the bigger and smoother the dome on top, the higher the voltage and longer the spark. Be sure to google it.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] Why does Bill Clinton link my ethanol subsidies to food riots?
"We have to become energy independent" but "we don't want to do it at the expense of food riots," the former President told an agriculture conference Thursday. He urged farmers to consider the needs of developing countries—the implication being that the diversion of corn to ethanol production limits food supplies and artificially raises prices.
No kidding. At the same gathering, Department of Agriculture chief economist Joseph Glauber did the math. Despite a forecasted 4% increase in corn planting, Mr. Glauber expects corn used for ethanol to hit a record five billion bushels in 2011-12, or more than one-third of total U.S. production, thanks to renewable fuel mandates and tax incentives. Corn prices recently hit two-and-a-half-year highs.
Liberals are politically retarded.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] Why is Hydro-energy considered as an indirect source of energy?
What are the steps involved in converting hydro-energy to electrical energy?
Hydro energy is rarely converted directly into work at the point of use. That would require having the machines that require the energy located right at the place where the energy is extracted from the water. For example, a saw mill used to be located right next to the river where moving water could directly turn a wheel to power the mill. But these days, it is far more common to first convert the energy of the water into a more mobile form so that it can be distributed to a remote location where it is more conveniently used. For example, the potential energy contained in water behind a dam is converted into electricity by passing it thru a turbine first, and then that electrical energy is sent over wires to an electrical grid where it can be used by multiple users at remote locations. Because the potential energy contained in the water is first converted into electricity, and then later used to do work, that energy is being used indirectly. In another example, water flowing in a stream or river has kinetic energy. This energy can be used directly to run a paddle wheel in a factory located right on the river, but it is more likely to be used first to turn the turbine of an electrical generator which produces power that gets distributed to distant users to perform work. Once again, that would be an indirect use of the hydro energy.
At Lumo Energy we love our planet and we know that you do too! So for all the planet lovers out there, we have Green Energy packages to suit your needs and your budget too. We offer two different Green Energy packages: Lumo Life 10 & Lumo Life 100. Now you have the option to be planet friendly when using your energy.
So what makes green energy so GREEN? Green Energy is derived from renewable sources, which means the energy comes from sources that will never run out, such as the sun, wind, biomass (waste), wave power or hydro (tidal power).
Now that you know what green energy is, how does it work? The answer is: exactly the same as your current electricity supply. The only difference is that instead of non-renewable energy sources feeding into the grid, Lumo Energy will purchase energy from renewable sources on your behalf to feed into the grid that powers your home.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] Is an article about renewable, clean energy/biofuels considered an informative article?
I was asked for a school assignment to choose an informative article on a topic that interests me and answer some questions about it. I picked a National Geographic article called Green Dreams, which is about future forms of renewable energy. go google the article if you don't know what I'm talking about. I'm just trying to make sure that I actually picked an informative article. Thanks!
Heck yes that is definitely informative! And good for you for doing your part to educate the general populous on important environmental issues.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] I'm doing a science project on green housing...?
We have to write a paper and make a poster/or a model of a house that uses materials to make it more energy efficent. What are some materials I could make/draw/symbolize for my project other than like solar panels? This will help alot!
ECO FRIENDLY HOUSING
There are many examples of houses made cheaply using local materials such as houses made from bamboo http://www.bambooliving.com/bambootech.html http://www.inbar.int/housing/main.htm http://www.bioversityinternational.org/publications/Web_version/572/ch38.htm Or Straw bale houses. http://video.google.com/videoplay?docid=-4673361259827571538 http://www.balewatch.com/ http://www.greenhomebuilding.com/strawbale.htm
Beautiful villas are build out of Adobe (Mud and sticks)with thatched roofs ,that are supremely insulated. http://www.world-housing.net/uploads/adobe.pdf?pr=Array http://www.kstrom.net/isk/maps/houses/pueblo.html http://sicarius.typepad.com/althouse/2007/07/adobe-floors.html
Very green housing partly with living roofs to blend in with the environment. Maximum 3 stories high,including a basement. a perfect example of this type of development is described by William McDonough: The wisdom of designing at the end of this tape,http://www.youtube.com/watch?v=IoRjz8iTVoo
William McDonough is an Architect who designed a city in China that blended totally into the landscape ,the farmland ending on top of all the equal level roofs ,with the farmers moving about on bridges
All the rooms would have the sun at least once a day,The city to utilize all their own byproducts as gas for cooking or compost With solar energy to power the lot
The land above would produce all the food and meat for the city
A totally auto sufficient concept ,with agriculture build in in a sustainable way.
A beautiful solution to Urban spread,(Be patient ,he does not go into this until the very end of the video)
LIVING ROOFS is a great solution to utilizing space as well as insulation against either heat or cold ,for the accomodations, green lawns is extravegant unless you got a goat grazing up there (got friends in south Africa who got that)
It means slightly different construction with concrete roofs at a very gentle slope (for drainage) damp coursing the concrete with black plastic,(Although the Aztezs used moss) installing irrigation systems.and leaving easy ways up to the roof ,with ramps
The walls and reinforced corner pillars must be of sufficiant strengh to support the extra weight ,as should the cross beams under the roof . If you decide to go the full living roof way which means at least 1/4 of a meter of soil to support the weight of the wet soil. No more than 3 stories is recommended before doing the living roof .
have the slope in a Northern direction to make full use of the sun(depending which hemisphere you are in,,and so that you could also incorporate solar panels.
But you can also put lots of flowerpots up if you just want some flowers ,standing on planks (the simple small way)
URBANISATION IN A SUSTAINABLE ,AUTOSUFICIENT & HEALTHY MANNER
Why this is recomended
They did some experiments with rats in highrise building conditions and after the 3rd story they began to get weird by the time they were on twenty they went insane and ate their own babies .
this gives you some idea what the bosses must be like in the penthouse offices
So 3 stories is a reasonable healthy hight for humans they have discovered BOTH MENTAL AND PHYSICAL HEALTH
so we cannot put to many people on top of each other technically it is an impossible task to ensure a continues supply of good air for everybody and the mental effects are drastic , but we can blend people into and under the landscape
More ideas on Eco Housing are Earthships http://www.earthship.org/ http://www.youtube.com/watch?v=Rlrhxqat_6A http://www.earthships.com/ http://www.greenhomebuilding.com/earthship.htm
Imagine a home that heats itself, that provides its own water, that grows its own food. Imagine that it needs no expensive technology, that it recycles its own waste, that it has its own power source. And now imagine that it can be built anywhere, by anyone, out of the things society throws away.
Thirty years ago, architect Michael Reynolds imagined just such a home – then set out to build it. A visionary builder Reynolds has been fighting ever since to bring his concept to the public. He believes that in an age of ecological instability and impending natural disaster, his buildings can – and will – change the way we live.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] What will happen if suddenly sun is removed from our solar system?
What will happen if suddenly sun is removed from our solar system. Of course we will be unable to see it after 8 minutes. But what about it's gravitational pull will it also require 8 minutes to disappear. What is the speed of gravity?
I guess such disappearance is against law of conservation off mass & energy.But still assume that Sun disappears[:d].
Please explain it in a detailed way.
Thanks
Although gravity might act instantly most of us will not notice any thing until the sunlight went out. Scientists would determine the exact nanosecond that the sunlight went out and the exact nano second that the sun's gravity ceased to affect the earth.
Some life on earth may be affected by the sudden reduction in sunlight.
Afterwards each planet and its moons move onto a new trajectory as a system. No planet is going to run over any of its moons, all its moons are safe, no one will get hurt.
Some planets may form orbits about others, these orbits are likely to be highly elliptical, but eventually groups of planets will find themselves orbitting a star, or a group of stars.

Biochar - Know About The Green Energy Niche That Is Growing With A Rapid Pace
The ever increasing pollution is a great threat to the lifestyle of humans as well as animals. These days various office building, homes, towns and cities are using the green energy in order to make energy more efficient and safer. Many countries are now conducting projects and researches with the help of which they can cut down green house gases to prevent the environment from its harmful effects.
Harmful gases which are present in the environment are also responsible for Ozone depletion. It is now time to take some measures through which we can stop the environment from becoming polluted and poisonous. Researches and tests that are being carried out have proved that chicken manure can actually help us to fight pollution and prevent ozone depletion.
In this article, I would mainly want to provide you some important information on chicken manure and "Biochar".
1. Great benefits of Biochar Chicken manure is a beneficial product that can really help us to fight against the green house gases. A machine has been invented by scientists that convert the chicken manure into a substance which is known as Biochar. This substance is a very good fertilizer and it can also trap harmful gases which are responsible for the depletion of the ozone layer. It can efficiently trap carbon which can really be harmful for our environment.
2. Use of large machines This is an economically friendly technology that comes with great benefits. In order to manufacture Biochar you need big machines that can burn the chicken waste to convert it into the final product. Such machines are really very costly but with the help of government funding and grants, chicken framers can now install them in their farms.
3. The machine can also be used for heating purposes The machine not only manufactures Biochar but is can also be used for heating purpose. It is used by farmers to heat up the chicken coops. This technology is very beneficial for the framers as it helps them to earn extra profits.
4. Other materials used to produce Biochar It has been found out that other materials like switch grass and wood can also be used for manufacturing Biochar. The waste from wood, grass and chicken is burned very slowly at a low temperature. This burning of chicken manure traps the carbon and prevents it from escaping into the atmosphere.
The future of this technology is very bright that is why the government must assist farmers so that they can install more machines in the farms to produce Biochar.

How much Grants can you get from the Government for Home Solar Panels
To be able to purchase a full solar power panels system to run your whole homes electricity requirements, you'd need to make an investment of tens of thousands of dollars for a medium to large home. As soon as you have installed your system you may discover that it could take up to 30 years prior to your system has paid for itself. As a result of this many people are put off obtaining panels for their houses.
Just how much Will The Government Provide you with In Rebates and Incentives
The government has recognized that this really is a problem and have provided rebates and incentives for renewable energy systems like solar panels and wind turbines. In some states, you are able to obtain as much as 80% back through rebates and incentive programs. This makes obtaining panels much more viable for lots of people.
How you can Decrease Your Costs Even Further
If you are a do it yourself enthusiast, you can reduce the cost of your panels system by over 60%. An average 100watt panel will cost you in the region of $600-$800 to purchase and just $200 to develop. Homemade solar panels work just the same as shop stock and will produce the same amount of electricity.
How Rebates Work
Here is what you could anticipate. A system for $10,000 which produces around 1kw or 1000watts will get you
-30% tax credit from the federal government
-$3/watt rebate localized incentive via DSIRE.org
-$1000 State Property Tax Credit for a photovoltaic system.
As a result of these various incentive programs, the price of the solar panel system will be $10,000 less Fed Credit of $3000, Utility rebate of $3000 and state tax rebate of $1000. The total price of the system is only $3000 after all those incentives.
The government also considers the physical aspects of your installation before granting solar subsidies. Your system efficiency also dictates just how much you'll be able to get back so the geographical location of your house, weather conditions, obstructions, shadings, angle of installation, module efficiency, and other aspects that could impact your solar system efficiency also dictates the amount of subsidy you get for your system.

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate] Crops as renewable energy.... need info about ethanol and biomass?
i really need some information about renewable energy but only biomass if you know anything that might help please let me know. the questions i need answered are 1) what crops are used in the US for renewable energy, 2) what are the pros and cons of using crops as energy 3) any other information on biofules
Crops for renewable energy are generally a bad idea. They appeal to those who think there must be a way of solving our energy and climate change problems without interfering with business as usual. As such they appeal to our politicians who would otherwise have to announce the end of economic growth. Naturally politicians fear that they would lose votes conveying such a message and they latch on to any alternative.
Why are energy crops a bad idea? Because they push up the cost of food and they encourage further deforestation. Increased food costs impact more on the poor and lead to social unrest and war which impacts on everybody. Deforestation adds to global warming which will also cause economic and social upheaval.
The only real solution to the energy crisis and global warming is to adopt simpler, less wasteful lifestyles and to generate energy from sustainable sources such as wind, wave, tide, geothermal, solar and hydro sources. The good news is that we can make a start individually. We will find simpler, less wasteful lifestyles more fun than trying to keep up with what the neighbours spend and we will demonstrate to governments that there are votes in adopting more sustainable policies instead of jumping from one crisis to another.

Top Three Reasons Solar Energy Is Going to Help Countries Go Green
People are talking about it almost every day and the media is just flooded with continual news of Energy related topics. To be honest, some of the going green ideas are a little far fetched and some that are just downright bizarre.
People need to keep in mind that the Government may be helping to give incentives the whole going green trend and so there is some money being spent on some really abstract ideas. I would just like to point out that results are what is going to bring demand, not just new Green products. For this reason I think Sun gathered Electricity is going to one of the key ingredients to help other countries go green.
Top Three Reason Solar Energy is Going to Help Countries Go Green
1. Solar Energy is continuing to advance in technology and efficiency. The government is spending big bucks to discover new methods of green energy and solar energy is a great beneficiary. A funny thing to note about advances in solar energy possible the biggest discovery recently was mad by a kid in a school science project. The basic thing to see here is that as good a solar power already is, expect it to get better.
2. Electricity from Solar source is not only in panels but now shingles too. Dow Industries just unveiled its new solar shingles that are supposedly easy to install and great for home energy efficiency. It may not sound big to many, but some estimates show that over $5 billion of these Solar shingles will be sold by the year 2015
3. Solar Energy is available anywhere there is sunlight. Most traditional types of electricity generation require huge infrastructures and miles of wires to deliver the electricity to the users. This is not so with solar energy. This is huge news for the remote areas of the world in Africa or the Amazon. New Villages are now experiencing electricity for the first time thanks to solar panels.

Another great form of renewable energy is biomass, it involves the derivation of fuel from animal and crops fossil which is then converted to fuel for human use. While this might sound good and impressive as a source of energy it also has a lot of disadvantages worth considering before you decide if it is right for you or not.
1. It Produces Greenhouse Emission
One of the greatest disadvantages of biomass is that it produces greenhouse emission which brings about more damage to the atmosphere and also increases global warming. It is truly a good form of energy but which energy is good at the risk of human lives?
2. Biomass Collection is Difficult Another disadvantage of the biomass is the collection process, most energy sources don't require you to do any collection but the process of collecting the biomass resources can be a very strenuous one.
3. Problems With Availability of Crops Biomass also has another major disadvantage in regards to the crop availability, the crops needed are not available throughout the year and this can be a great and challenging problem. Having fuel is one thing, having a stable and reliable fuel is another thing.
4. It is Expensive The process of collecting the biomass resources, creating the machine that will process and convert the energy into useful energy is very expensive and can be below the reach of the average person, and this makes biomass energy even less important.
5. It is not Efficient Biomass energy is also not that efficient because of the type of energy it produces and the rate at which it produces it. The initial energy produced can be very low and almost useful and it also take additional time, effort and resources to convert the energy derived into a useful one.
Green energyis referred to energy produced in a manner that does not pollute the environment. It's a subset of renewable energy that may represent the energy sources and technologies with highest environmental benefits. The usual types of green energy that comes in mind are solar, wind, geothermal and hydro energy. But there are more types of green energy such as nuclear energy, ocean energy, and biomass or energy from solid wastes.
One of the key benefits of green energy is that, it's totally safe for the environment. Because its main goal is to generate power with little pollution as much as possible. Using green energy, can help in mitigating climate change. Moreover we can decrease our dependence on oil since it is renewable, there are plenty of sources that can supply the increasing demand of energy worldwide. Whereas with the energy derived from fossil fuels, aside from the fact that it's expensive and limited it also pollutes the environment.
It's true that green energy facilities are expensive to build, however these facilities only require less maintenance so it won't cost that much to operate it. Added to that, there are other byproducts of these green energy facilities, such as distilled water and high alloy steel wire. Aside from the green energy produced, these other products can be used in other industries.
It's a great thing that technologies nowadays are improving when it comes to green energy production. An example of this is the biosphere gasification technology. It's a gasification process that has no toxic leftovers which cause leachate issues and it uses limited-oxygen environment which limits atmospheric emissions. Biosphere technology also helps clean up the environment by destroying solid wastes to produce green electricity and other by-products.
